Example two
The principle of this embodiment is the same as that of the first embodiment, and the main differences are as follows: in this embodiment, a plurality of fresh air blowers 9 are arranged in the fresh air pipe 6. As shown in fig. 11-13, in the present embodiment, a plurality of in-pipe fresh air fans 9 are provided, and the fresh air module 3 located indoors is only provided with the fresh air intake cavity 5, and is not provided with the fresh air fan assembly 4; at the moment, the fresh air inlet cavity 5 is communicated with the fresh air pipe 6 and the indoor unit of the air conditioner. That is, in this embodiment, the fresh air is driven only by the plurality of in-duct fresh air fans 9 in the fresh air duct 6.
In this embodiment, the fresh air duct 6 includes an outdoor section located outdoors, a wall body section penetrating through the wall body, and a transition section connecting the outdoor section and the wall body section. The outdoor section and the wall body section are equal-pipe-diameter sections, namely the indoor section and the wall body section keep the respective pipe diameters unchanged; in this embodiment, the indoor section and the wall body section are linear pipelines and keep their respective pipe diameters unchanged. In this embodiment, the pipe diameter size of the outdoor section is greater than the pipe diameter size of the wall body section, and the transition section connects the outdoor section and the wall body section, that is, the pipe diameter of the transition section changes in the transition, and the transition section is an unequal pipe diameter section.
The fresh air fans 9 in the pipes rotate around the axis and are arranged in sequence; namely, a plurality of in-pipe fresh air fans 9 (axial flow fans and/or diagonal flow fans) are arranged in series; the diameters of the fresh air fans 9 in the pipes are all D. In this embodiment, the fresh air fans 9 in the pipes are all arranged at the outdoor sections with equal pipe diameters.
As shown in FIG. 13, the fresh air fans 9 in the plurality of tubes are sequentially marked as 1, 2, 3 and 4 … … n from beginning to end, wherein n is greater than or equal to 2; i.e. in the direction from the second end to the first end or in the direction from the first end to the first end. The size of n is determined according to the actual length of the fresh air pipe 6, the actual distance between the fresh air fans 9 in the pipes, the performance of the fresh air fans 9 in the pipes, the comprehensive effect of the indoor unit of the air conditioner and the like.
Wherein, on the rotation axis of the new air fan 9 in the tube, the distance between the new air fan 9 in the ith tube and the new air fan 9 in the (i + 1) th tube is recorded as the ith adjacent distance Li(ii) a Wherein i is more than or equal to 1 and less than or equal to n-1; wherein L is1、L2、L3、L4……Ln-1In (1), at least one belongs to (0, D)]。
The other adjacent spaces may be equal or unequal, and are set according to actual requirements. When the adjacent distance between the fresh air fans 9 in the tubes is within (0, D), turbo-charged airflow can be formed between the two adjacent fresh air fans 9 in the tubes, so that the fresh air volume introduced from the outdoor is obviously improved.
The limitation of the adjacent distance of the fresh air fans 9 in the tubes is suitable for the condition that the fresh air fans in the tubes are arranged on the same rotating axis and the diameters of the fresh air fans 9 in the tubes are equal. In this embodiment, the in-tube fresh air fan 9 is disposed in the equal-diameter section, and also can be disposed in the unequal-diameter section or two equal-diameter sections with different diameters. When the air inlet mesh enclosure 81 and the air outlet mesh enclosure 82 are arranged in sections with different pipe diameters or two sections with different pipe diameters and the same pipe diameter, the sizes of the air inlet mesh enclosure 81 and the air outlet mesh enclosure 82 of the fresh air fan 9 in the installation pipe are different due to the connection with the fresh air pipes 6 with different pipe diameters, but the diameters of the fresh air fans 9 in the installation pipes are equal.
In the embodiment, a turbo-charged airflow can be formed by connecting a plurality of in-pipe fresh air fans 9 (axial flow fans and/or diagonal flow fans) in series, so that the fresh air volume introduced from the outdoor can be remarkably increased; in addition, the fresh air fan 9 (axial flow fan and/or diagonal flow fan) in the pipe is arranged in the pipe section of the fresh air pipe 6 which is positioned outdoors, so that the noise generated at the indoor side can be avoided, the indoor fresh air noise can be effectively controlled, and the noise value is obviously reduced.
